Fish Passage Flows


The Fish Passage Flows portion of the Crossing Input Window is where you enter the Low and High Fish Passage design flows. Profiles will be generated for each of these flows and fish passage conditions will be examined at all flows between them.

Standard engineering practices dictate that culverts need to be designed to pass water and in many cases wood, bedload and debris at high flows. Commonly the event with a 100-year return period is the maximum design flow. You can use FishXing to model additional flows by using the Flow Calculator, which is located on the Output Summary Window.
